   Q: The flow rate of my system is about 60L. I want to choose a small air cooler, but the flow rate can meet my requirements and is used to cool the oil return of the hydraulic motor.

   A: What is the temperature difference? Oil inlet temperature? Ambient temperature?

   Q: The temperature difference is 20, the oil inlet temperature is 60, the oil outlet is 40, and the ambient temperature is about 30-40.

   A: 60L is the flow of the pump or the return flow of the system?

   Q: My side is a pump string motor, so the flow of oil return and oil return is the same.

   A: Yes.

   Q: The system power is 20 kilowatts. I will calculate the 30% loss as heating power. I do n’t know how you generally choose this type?

   A: It can be estimated like this.

   Q: Because I may not move continuously for a fixed time, the longest may be about an hour, so I want to choose a small heat sink. Yours will be more professional, so I would like to consult your opinions.

   A: There is also a more accurate algorithm. The heat dissipation power P = 0.028 × Lx (V in-V out) = 0.028x60x (60-40 =) 33.6kw. The first test is contradictory to the system power of 20kw, so the accuracy of the data provided is important. This is an impossible requirement.

   流量要50-60升这样,你们这边有吗? Q: I'll choose one like 1-2KW, and the air cooler should have a flow of 50-60 liters. Do you have one? My side is a newly designed model, so how much the temperature difference will be, I can only estimate one value for the time being.

   A: Select HD1018

   Q: 6KW is too big

   A: For this model, you should choose 60 according to the flow rate. Considering the safety issue, it is normally 60x2 = 120L. The core structure and filter of the radiator are similar, similar to the capillary structure.

   Q: Yes, it should mainly affect the pressure drop?

   A: There is also this reason.

   Q: Let me ask, should I lay this radiator flat? Are there any specific requirements for the placement method?

   A: It can be laid flat.

   Q: I should choose a 100L 4KW. It should not be a problem.

   A: The heat of the hydraulic motor is very harmful. If a 20KW motor is dedicated to supply pressure oil to the hydraulic motor, the heat loss is often more than 30%. Because when the motor is working, it is always under pressure

   Q: 6KW will be safer.

   A: It also depends on the size of the fuel tank. There is less oil and the temperature rise is relatively high.

   Q: The fuel tank is too small, about 1.5 times. 。 Temporarily choose AH1012DC air cooler .

   A: OK, you can try it first.
